A CORPORATION OF NEW YORK.

PROCESS. FOR MAKING ROLLED STEP-JOINTS.

Application filed January 27, 1920.

T 0 all whom it may concern:

Be it ,known that I, BANOROFT G. BRAINE, citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Processes forMaking Rolled Step-Joints, of which the following is a specification.

This invention relates to a method of manufacturing compromise or steprail joints from rolled bars thereby admitting of a distribution ofmetal to provide bars of this character which are of greater strengthand efliciency than the cast type of joint bars in common use.

Primarily the invention therefore contemplates a new process for makingstep joint bars for railway rails which enables the manufacturer toutilize the rolling mill practice to effect proper distribution of metalthroughout the bar in an expeditious I and economical way while at thesame time providing for the formation of the bar in a manner wherebyboth outer and gage-side bars for opposite joints may be produced by thesame operation.

lVith these and other more general objects in view which will readilyappear to those familiar with the art the invention consists in thenovel process steps'hereinafter particularized and which may be formedin connection with suitable apparatus and equipment in a rolling mill.

Various well-known and conventional instrumentalities maybe utilized incarrying out the invention therefore the accompanying drawings more orless diagrammatically illustrate the several phases of the methodemployed.

Accordingly I Figure 1 is a diagrammatic view of a bar showing the jointlengths laid off by dotted lines.

Fig. 2 is a perspective view of a bar'unit comprising two joint lengthsfor the gageside and indicating by dotted lines the line of shear cut tobreak up the unit into two joint lengths.

Fig. 3 is a perspective viewsimilar to Fig. 2 showing the bar unitsevered.

Fig. 4 is aperspective view similar to Fig. 2 showing a bar unit for twooutside bars.

Patented Dec. 14, 1920.

Serial No. 354,447.

Fig. 5 is a perspective view of the unit of Fig. 4 severed into the twooutside bar lengths. I

Fig. 6 is a perspective view of a pair of joint bars formed inaccordance with the present method, the bars being viewed from thegage-side of the joint.

Fig. 7 is a view similar'to Fig. 6 looking at the outside bar of thejoint.

Similar reference characters designate corresponding parts throughoutthe several figures of the drawings.

In order to provide for joining rails of dissimilar section in track itis necessary that the joints which are termed step or compromise jointsbe so' constructed as to properly fit the fishing spaces andrail-bearing surfaces upon both sides of the dissimilar rails, and, onaccount of the running surfaces and inner sides of the heads of thedissimilar rails being in line, it is likewise necessary to provide theouter joint bar of different offset conformation from that of the inneror gage-side bar, thus involving in each step joint two bars commonlyknown as outside and gage-side bars. This dissimilarity of the outer andgage-side bars has heretofore made it very diflicult to economicallymanufacture such bars except by casting processes, but according to thepresent invention it is proposed to make these bars by a rolling millprocess whereby the proper distribution of metal may be provided forwhile at the same time facilitating the making the different bars by thesame operation.

I Inexplanation of the novel steps by means of which the aims of thepresent invention are attained it will be observed by reference to Fig.1 of the drawings that the pri-,

mar feature'of the invention is to roll a continuous bar with thenecessary prescribed off-setting according to the section of the railsfor which the same is adapted, and

then to sever the bar centrally between the off-sets,- thus breaking upthe entire rolled bar into rail joint len ths, each of which includes abar section" tting the fishing of the larger rail and a bar sectionfitting the fishing of'the smaller rail.

Referring more fully to thenovel steps of the process which aresubstantially the same for making both the inside and outside jointbars, it will be noted from F ig; 1 of the drawings, that according tothe invention claimed herein, a bar blank is subjected to the action ofroll passes to thereby provide a bar with the necessary offsets, bothvertically and laterally, each offset-portion of the bar'being of fullrail joint length, as indicated at aa, in said Fig. 1 of the drawirfligsWithreference to the character of the 0 -setting, this necessarilydepends upon the section of rails to be united, it being observedhowever, that in the case of thegageside bars only a verticaloff-setting may be necessar, while the outside bars usually aredeflected vertically as well as laterall Y to not only meet thedifferences in the fis ing spaces of the rails but also the differencein the width of the rails. In either event however, the initial step ofthe process remains the same, and the effect thereof is to produce acontinuous bar having the general characteristics of the bar shown inFig. 1 of the drawings. 7

After the bar has been formed in accordance with the step above setforth, it is proposed to sever or cut the same at points midway betweenthe off-setting shoulders, thereby producing the necessary jointlengths. While the shearing of the rolled bar occurs successively midwaybetween the shoulders of each ofi'set section designated a-a in Fig. 1,the result accomplished is in effect to produce units of constructionextending between the lines 0.0, and when these units of construction,as per Fig. 2, are bisected on the shear lines C-C each unit ofconstruction is broken up into two joint bars adapted respectively foruse in joints at opposite sides of the track. By this step of the methodtherefore, the separate gage-side bars D and E are formed, each being ofthe required length to properly join or connect the ends of thedissimilar rails. The cutting or severing step by which the individualjoint bars are formed may be carried out by any of the well knownshearing instrumentalities employed for cut ting or severing rail jointbars.

The outside bars of the joint may be formed by the same method employedfor the gage-side bars, as illustrated by Figs. 4

and 5 of the drawings. From these figures it Will be observed that thebar blank which results from the severing of the originally rolled barstrip may be severed on the line 0 0 to thereby provide the outside barsF and-G for the joint pairs. As previously indicated the outside barsare off-set'laterally as well as vertically in the off-setting step ofthe method, and are then severed in the' same manner as proposed inconnection with the gage-side bars, namely at the inter- .mediate partof the off-set portion. Thus in this way the outside bars of a pair ofjoints are formed. p

Also in the case of one-end insulated joints where a space is desiredunder the head of one rail for insulation, the joint barscanbe 7 rolledby the same general method and then also cut to provide right and leftbars for accommodating the insusite joint pairs may be obtained. Thismay be clearly observed from Figs. 6 and 7 of the drawings wherein thegage-side bar forms one side of one of the jloint pairs while in Fig. 7the gage-side bar i represents the gage bar of the other joint pair.Similarly the outside bar F of Fig. 7 and the outside bar G of Fig. 6are formed in the sameoperation. e

I claim 2-.-

1. A process for making step joint bars which consists in firstsubjecting the blank to a rolling pass producing a continuous rolled barhaving off-sets therein at regular intervals, and subsequentlysevering-the bar,

at points intermediate the. locations of therolled bar having off-setstherein at regular 7 intervals and subsequently severing the bar midwayof the off-set portions.

3. A process for making step joint bars which consists in subjecting abar blank to means, for producing off-sets therein, and subsequentlysevering the deformed bar at themedial portion of the off-sets, therebyproviding in one operation the bars of opposite joints.

4. A process for making right and left step joint bars which consists infirst deforming a bar blank to provide off-sets therein, andsubsequently severing the bar at the medial portion ofthe off-sets tothere: by provide right and left bars of. opposite joints.

In testimony whereof I hereunto affix my signature in the presence oftwowitnesses. V
